Medical terminology test #1 Flashcards
Terms built from word parts
Majority of terms in use today are from parts of the Greek and Latin language
Eponyms
are terms derived from a name or place.
ex: west Nile vires named after the 1st geographical location it was identified
Acronyms
are terms formed from the first letter of a phrase.
ex: such as laser(light amplification by stimulated emission of radiation)
Modern language
refers to terms from the English language, which are often descriptive of technology and procedures
ex: nuclear medicine scanner
Terms NOT built from word Parts
(cannot be easily translated to find their meanings)
4 word parts
most medical terms categorized as built from word parts consist of some or all of the following components:
1)word root
2)suffix
3)prefix
4)combining vowel
word root
is the CORE of the word. the word root contains the fundamental meaning of the word.
ex: in the word=play/er
play is the word root
in the medical term: arthr/itis
arthr(which means joint) is
the word root
in the medical term: hepat/itis
hepat(which means liver)
is the word root
*the word root is the core of the word. All medical terms have at least one word root
Suffix
is a word part attached to the end of the word root to modify its meaning
ex: in the word- play/er
er is the suffix
in the medical term:hepat/ic
ic (which means
pertaining to) is the suffix
and hepat is the word
root for liver; therefore,
hepatic means pertaining
to the liver
in the medical term: hepat/itis
itis(which means
inflammation) is the
suffix. the medical term
hepatits means
inflammation of the liver
the suffix si used to modify the meaning of a word. Most medical terms have a suffix.
*suffixes frequently indicate:
*procedures: such as scopy, meaning visual examination, or tomy, meaning incision
*conditions: such as itis, meaning inflammation
*diseases: such as oma, meaning tumor.
Prefix
is a word attached to the beginning of as word root to modify its meaning.
ex: in the word: re/play
re-is the prefix
the medical term: sub/hepat/ic
sub-(which means under)
is the prefix, hepat is the
word root for liver, and -ic
is the suffix for pertaining
to. the medical term
subhepatic means
pertaining to under the
liver.
the medical term: intra/ven//ous
intra-(which means
within) is the prefix, ven
(which means vein) is the
word root, and -ous(which
means pertaining to) is
the suffix. the medical
term intravenous means
pertaining to within the
vein
*a prefix can be used to modify the meaning of a word. Many medical terms do not have a prefix.
*prefixes often indicate:
-number: such as bi- meaning 2
-position: such as sub- meaning under
-direction: such as intra-meaning within
-time: such as brady-meaning slow
-negation: such as a- meaning without
Combing vowels
is a word part, usually an 0,used to ease pronunciation
*the combining vowel is:
-placed to connect 2 word roots
-placed to connect a word root and a suffix
-NOT placed to connect a prefix and a word root
ex: the medical term:
oste/o/arthr/itis, 0 is the
combining vowel used
between 2 word roots
oste(which means bone)
and arthr (which means
joint)
the medical term: arthr/o/pathy:
0 is the combining vowel
used between the word
root arthr and the suffix
-pathy (which means
disease)
the medical term: sub/hepat/ic
the combining vowel is
not used between the
prefix sub- (which means
under) and the word
root hepat (which means
liver)
*the combining vowel is used to ease pronunciation; therefore, not all medical terms have combining vowels.
Vowels
are speech sounds represented by the letters a, e, i, o, u, and sometimes y
Guideline 1
connecting a word root and a suffix, a combining vowel is used if the suffix does not begin with a vowel.
ex: the medical term:
arthr/o/pathy
the suffix -pathy does
not begin with a vowel;
therefore, a combining
vowel is used
guideline 2
when connecting a word root and a suffix, a combining vowel is usually not used if the suffix begins with a vowel
*ex: the medical term: hepat/ic
the suffix -ic begins
with the vowel i;
therefore, a
combining bowel is
not used.
guideline 3
when connecting 2 word roots, a combining vowel is usually used even if vowels are present at the junction
ex: medical term:
oste/o/arthr/itis
o is the combining
vowel used, even
though the word root
oste ends with the
vowel e, and the word
root arthr begins with
the vowel a.
guideline 4
when connecting a prefix and a word root, a combining vowel is not used.
ex: medical term: sub/hepat/ic
the combining bowel is not used between the prefix sub- and the word root hepat
combining form
word root with a combining vowel attached, separated with a slash
learning medical terms built from word parts
*analyzing, defining, and building medical terms are used in this text to learn medical terms categorized as built from word parts.
analyzing medical terms
to analyze a medical term, divide it into word parts, and label each word part and each combining form.
1) divide the term into word part with slashes.
ex: oste/o/arthr/o/pathy
2)Label each word part by using the following abbreviations
WR=word root
P=prefix
S=suffix
CV=combining word
ex: WR /CV/WR/CV/S
oste/o/ arthr/o/pathy
3)Identify each combining form by underlining the word root and combining vowel, and then writing the abbreviation CF below the combining form.
ex: WR/ CV/WR/ CV/ S
oste/o/arthr/o/pathy
CF CF
cytogenic
producing cells
cytology
study of cells
dysplasia
abnormal development
epithelial
pertaining to epithelium
erythrocyte
red blood cells
erythrocytosis
increase in the number of red blood cells
